Improved blast circular cooling machine

Abstract

The present invention discloses an improved rotary forced-air cooler, which comprises a double layer trolley, a supporting beam structure, a material blocking proof air duct sealing plate arranged at the connecting part of the double layer trolley and an air supplying system, a double layer trolley unit static seal device and an air duct device. The supplying system structure is based on a rectangular beam, a triangle beam is arranged on the rectangular beam, and a plurality of ventilation channels are arranged on the bevel edge steel plates at the both waists; an air duct pipe is arranged on the air vent of the material blocking proof air duct sealing plate, an inclined plate inclining upwards from the air vent at the bottom part of the air duct pipe has a transition to a horizontal plate, a stopping ventilation fence is added to the air duct pipe at the side of the trolley; two rubber sealing parts with extended bottom edges are arranged at the outer sides of the lower parts of inner and outer sealing plates of the double layer trolley unit static seal device, an ash baffle plate which can move up and down is hung at the inner side; an air water sealing wave subduing device adopting a damping plate is arranged on the air duct device. The present invention further improves the sealing performance of the equipment, and reduces energy consumption and pollution.

Description

technical field [0001] The invention belongs to a blast ring cooler used for cooling sintered pellets in the metallurgical and mining industry. Background technique [0002] Blast ring cooler is one of the equipments for cooling sinter pellets. China's No. 00224627.9 utility model patent document discloses a new type of air blast ring cooler. This machine has made better improvements to the outstanding problems of traditional blast ring coolers, making the blast ring cooler technology reach the a new level. The new blast ring cooler includes double-layer trolley, circular air duct, air supply system and other components. After running for a period of time, the new blast ring cooler found that there are still some unsatisfactory places: [0003] 1. The supporting beam of the trolley is a beam with a triangular cross section, and the three sides of the beam are all blind plates, which only support the trolley. When working, the trolley grate plate and the inclined surface ...

AI Technical Summary

Problems solved by technology

The support beam structure of the trolley has good airtightness and air permeability; the anti-blocking material air duct sealing plate can solve the problem that the material will block the vent on the sealing plate when the trolley is unloading; the sealing structure of the unit static sealing device can make The unit sealing area ensures a good sealing effect and prevents the scattered red ore from contacting and burning the rubber seals; the air duct water sealing wave suppression device has a good sealing effect and can prevent the water in the water seal from being affected by the wind in the air duct vibrate or resonate
